Acronym of ESIM

( Embedded SIM ) An eSIM (embedded SIM) is a form of SIM card that is embedded directly into a device as software installed onto an eUICC chip. First released in March 2016, eSIM is a global specification by the GSMA that enables remote SIM provisioning; end-users can change mobile network operators without the need to physically swap a SIM from the device. eSIM technology has been referred to as a disruptive innovation for the mobile telephony industry. Most flagship devices manufactured since 2018 that are not SIM locked support eSIM technology; as of October 2023, there were 134 models of mobile phones that supported eSIMs. In addition to mobile phones, tablet computers, and smartwatches, eSIM technology is used for Internet of things applications such as connected cars (smart rearview mirrors, on-board diagnostics, vehicle Wi-Fi hotspots), artificial intelligence translators, MiFi devices, smart earphones, smart metering, GPS tracking units, database transaction units, bicycle-sharing systems, advertising players, and closed-circuit television cameras. A report stated that by 2025, 98% of mobile network operators were expected to offer eSIMs.
